And assuming 1 leg calls originating from a dialer would generate 80megabits of RTP (at the IP layer even more on the wire), and approx 50K PPS. Assuming 2 leg’d calls bridging media 160megabit and 100K PPS of just RTP... <br><br>But then we have to extrapolate peak concurrent from 1000 CPS... Assuming dialer traffic again, 75% ASR and 20 second ACD, and lets assume the 25% are just hard failed for the calculation (no early media on these) that gives us 750 new calls/sec and over the course of 20 seconds we accumulate 15,000 concurrent calls..<br><br>So lets take that and extrapolate bandwidth and PPS requirements for single leg’d calls of 1.43Gig/sec (on the wire) and 750K PPS so that’s going to exceed the bandwidth of a GIG-E connection so you’d have to break this into 2 RTP endpoints in sofia, and make sure you switches/routers could handle the PPS loads. <br><br>Double that to 2 leg calls and you have 2.86G/sec of RTP (again on the wire including UDP, IP, ethernet framing over heads) and pushing 1.5million PPS.<br><br>Here again this dictates at least 3 gig-e NICs on your FS box. Is this possible? I’m sure it is with the right hardware configuration... But lets step back a minute and really consider what is going on...<br><br>You are now putting approx over $2000/hr of traffic on a very expensive box that can and will at some point fail. Why are you doing such a thing? You’re better off limiting rates to sub 1000 CPS, (say 500CPS) deploying 3 boxes to handle the load in n+1 configuration, and if you lose a box you arent losing $2000+ in revenue and cranky customers while you repair/replace the now dead machine.<br><br>Lets face it, you can purchase a colo a nice machine for say 200 to 300$/month (assuming bandwidth costs are the same as above so that’s a wash instead of trying to cram it all on box that ends up costing you 1000/month by the time you pay for the hardware and colocation expenses for it.<br><br><br><br><br><br>On 8/14/14 11:56 AM, "Russell Treleaven" <<a href="rtreleaven@bunnykick.ca">rtreleaven@bunnykick.ca</a>> wrote:</span><o:p></o:p></p><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'>1000 calls per second... no idea but I really doubt the network interface is going to be the bottleneck.<br>Not sure why you make a distinction here between sessions and connected.<br>To be clear you mean 5000 bridge calls correct?<br>Since media is not an issue I think you can just start testing with sipp and bwm-ng to see what is what.<br><span style='color:#1F497D'><br>1000 calls per second is a very big number.<br>Let us know how you make out.<br><br>Sincerely,<br><br>Russell Treleaven<br><br></span></span><span style='font-size:11.0pt;font-family:"Courier New"'><br></span><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><br></span><span style='font-size:11.0pt;font-family:"Courier New"'><br><br>On Wed, Aug 13, 2014 at 5:40 PM, Andre <<a href="andretodd@verizon.net">andretodd@verizon.net</a>> wrote:</span><o:p></o:p></p><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Courier New"'>1000 calls per second and 10000 sessions with 4000 connected.
